Andy Murray on experience of playing at Rafa Nadal Open

Former world No. 1 Andy Murray admitted to feeling tired and dealing with cramps following a shock round-of-16 exit at the Rafa Nadal Open. Murray, 32, won the opening set of his match against Matteo Viola before the world No.

240 stormed back to claim a 3-6 6-4 7-6 (3) win and progress into the Mallorca Challenger quarterfinal. The 32-year-old, who recently returned from a hip resurfacing surgery, was clearly having difficulties on the court with his movement but it appears to be nothing too serious.

"I'm cramping, (I feel) very tired," Murray said during his on-court interview when asked how he felt after the match. Murray decided to skip the US Open after losing his first two singles matches played against Richard Gasquet at the Cincinnati Masters and Tennys Sandgren in Winston-Salem respectively.

Murray, who entered the Mallorca Challenger seeking wins and form, beat Imran Sibille and Norbert Gombos in straight sets before he lost to Viola. "Yeah, it was good, I enjoyed it. I would have liked to have played more matches but it was good," Murray said, when asked about his experience of playing at the Rafa Nadal Open. "I played, you know, two competitive matches. Physically I need to get better."
